As requested, a few photos of this old, accurate and obscure watch:
I bought two watches from Japan at the same time. Of course, the Fedex man came, left a note and I had to go get the package at the depot. I was so excited I had to open things up in the car!
"Functionally, the 4s29 and 4s79 are very similar movements, both being handwinding only, with subsidiary seconds hand located at the 6 o’clock sub-dial and with a power reserve complication located at the 9 o’clock position. These movements have no day or date. The typical Credor 4s79 movement is rated to +15/-10 sec/day. The movement is gold plated high grade, and has 31 jewels compared to the 4s29 movement with only 29 jewels. A batch of 500 GBAY992 yellow gold and 20 GZAY999 white gold watches are the only 4s79 models in recent Seiko history (1980s-on) to be certified “Chronometer” and labelled as such at the 3 o’clock position. These are also the only 4s79 movement watches with a display case back."
You can search around and find more, but this is the gist of the watch.
